Epithelial cells

minuscule proportions; predominantly when observing eukaryotic and prokaryotic cells. A pathologist for example is a physician who examines cells and tissues to help other physicians make…

Introduction Cells are the building blocks of the diverse idea we call life, which means that they must be as diverse as life as well. Prokaryotic and Eukaryotic cells make up most of the life on this planet, and vary widely in function, while still sharing some similarities. Prokaryotic cells, although simpler and smaller, make up most life. A nucleoid region contains a loop of nucleic acids known as a DNA plasmid. Prokaryotic cells contain simplified ribosomes which free float in cytoplasm…

Relationship between cells Cells contain organelles these are the basis of a cell it contains many organelles and is basically the same a human these cells are the basic blocks of life cells are microscopic and what makes up tissues. Tissues are visible to the naked eye and are what creates us there are four main types of tissue connective epithelial nervous and muscle. Tissue makes up organs these are the what run us humans and every other living thing these keep them alive and have many…

(2) So the hydrophilic phosphate groups are both orientated towards the water present on the outside and on the inside of the cell What is the role of the phospholipid bilayer? (1) To act as a barrier to the entry of water soluble molecules such as glucose which can only cross membranes through protein channels Why is the term “fluid-mosaic” used to describe cell membrane structure? (2) Fluid because single phospholipids and proteins can move around freely within the layer, like it’s…

mitochondrial lineages are maternal. Thanks to the study of the mitochondrial genome it revealed that all humans carried mitochondrial DNA in their cells that dated back to a single…

Anatomy and Physiology are two branches of science and they provide the foundation for understanding the body’s parts and functions. Anatomy is the science of body structures and the relationships among them. Physiology is the science of body functions or how the body parts work. Anatomical position is the description of any region or part of the body in a specific stance. The anatomical position is the erect position of the body with the face directed forward, arms at the side, the palms of…

Connective Tissue and Epithelial Tissue Similarities: There are many similarities between connective and epithelial tissues. One of which is that both the connective and epithelial tissues have at least 2 layers. A similarity between the connective and epithelial tissues related to the organelles present and its functions is that they both have nucleus and mitochondria, so both need the production of energy to function and both contain genetic material. Also both the epithelial and connective…

bound and active GTP bound forms & are critical for cell proliferation, Survival & differentiation. Ras can activate downstream effectors including PI3K-AKT-mTOR and RAS-RAF-MEK-ERK…

g. Integral proteins and Transmembrane proteins Ans: D 6. This portion of the cell membrane enables cell membranes to produce chemical products. . h. Enzymes 7. Which of the following is a function of a membrane protein that binds with hormones and neurotransmitters? i. Receptors 8. This type of membrane protein helps to anchor proteins in the plasma membrane of neighboring cells to one another. j. Linkers 9. The characteristic of plasma membranes…

in the Eukarya domain and encompass all other organisms such as plants, animals, fungi and protists (Biology Department, 2015). The most effective way to distinguish between classes comes from observations made about their structure. Prokaryotic cells are smaller than eukaryotic ones; the typical prokaryote ranging from 100 nm - 10 µm, while a eukaryote could be anywhere from 10 - 100 µm (Reece et al., 2014). Prokaryotes are also less complex than eukaryotes in that they do not have organelles…
